Inventor: FUJIKAWA KATSUMI
IPC: H02M3/28
Filed: 1983-08-22
Abstract: PURPOSE:To prevent a load from burning out by providing a main power source output current detector for detecting the output current of a main power source and applying the signal as the input signal of a timing pulse delay time generator. CONSTITUTION:When an overcurrent is generated in a main power source circuit, a main power source output current detector 52A operates to turn ON a transistor 55. Thus, the signal is transmitted as an input signal of a timing pulse delay time generator 49, and a signal having a delay time determined by a resistor 50 and a capacitor 51 is outputted. Further, this signal is inputted to a shutdown circuit 35A, thereby turning a transistor 37 ON. Accordingly, the input of a comparator 39 decreases, the oscillation of a transistor 44 is stopped, thereby stopping the oscillation of a transistor 6, with the result that the output voltage of a sub current circuit is drooped, thereby preventing a load from burning out.

Filed: 1979-11-21
Abstract: PURPOSE:To reduce a change in the potential of a substrate and resultantly eliminate an adverse effect upon an element by forming a decoupling capacity inside an integrated circuit. CONSTITUTION:In an integrated circuit 1 built in a substrate potential generation circuit 2, a substrate potential fluctuates under the effect of power supply current 1BB running through a substrate. If the 1BB runs by time differential f, the potential change will be represented by the formula DELTAV=1BB.DELTAf/c. Then one electode 3 of the decoupling capacity is connected to the output VBB of the substrate potential generation circuit 2, while the other electrode 3 is earthed or connected to a high voltage current of the integrated circuit. For instance, the decoupling capacity is composed of a capacity C between a polysilicon 4 and a channel 5. Under this constitution, it is possible to reduce a potential change DELTAV in the substrate.

Abstract: PURPOSE:To equalize the light quantity of each light emitting dot light which reaches a photosensitive surface, and to realize printing high is quality, by specifying the relation of a provided pitch of a light emitting dot and a diameter of a light focusing lens. CONSTITUTION:A diameter D of a focusing lens is set to m/n (n is an integer) against a provided pitch (m) of a light emitting dot (f). For instance, in case of n=1, a provided position relation of a light source and a 'Selfoc(R)' lens array (SLA) is set so that one group in the oblique direction of the light emitting dot (f) passes through a contact being near the center of focusing lenses 12 which are superposed in two stages, and passes through in the diameter direction, by which with regard to any group of the light emitting dot (f), the position, relation to the focusing lens 12 becomes the same. Accordingly, in such a state, when a dot light is radiated onto the photosensitive surface through the SLA, and each group is compared, a pattern of a light quantity distribution of the dot light becomes all the same shape. That is to say as for the dot light of the light emitting dot (f) belonging to the same light emitting element string, even if the group is different, the light quantity is the same, therefore, by varying a light emitting state at every light emitting element string, the light quantity of all the dot light beams which reach the photosensitive surface can be equalized.

Title: Environmental testing device with water surface area variable type humidifier
Inventor: UEDA MASAKATSU
IPC: F24F6/02
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To reduce the amount of natural evaporation of water during low temperature operation, to diminish the dehumidifying load, to save energy and to reduce the capacities of a refrigerating machine and dehumidifier. SOLUTION: When a low humidity operating condition at relative a humidity of 40% or lower is set, for example, a surface area controller 23 automatically opens a solenoid valve 32c and closes a solenoid valve 32b simultaneously. Thereby, water in a second humidifying pan 32 is drained and supply of makeup water is stopped. As a result, water remains only in a first humidifying pan 31 and the surface area of water in a humidifier 3 is cut by half. Therefore, steam generation rate due to natural evaporation can be remarkably diminished, resulting in a decrease in dehumidifying load and in operating load of the dehumidifier and an evaporator. Then, a considerable energy saving can be accomplished because of a decrease in the dehumidifying load itself and operation of the small-sized dehumidifier and a refrigerating machine.
